AI Technical Summary
Existing drone propeller shields offer limited protection in open environments, cannot be removed which affects battery life and maneuverability, and are inconvenient for transport and carrying.
A propeller anti-collision protection cover was designed, which includes a support frame and a foldable annular shell. It can be detached and installed by magnetic connection. The support frame can be sleeved on the connecting seat, and the annular shell can protect the propeller in all directions. It can be folded when disassembled to reduce space occupation.
It enables quick installation and disassembly, reduces space occupation, facilitates storage and carrying, and provides effective propeller protection to prevent debris from being caught or causing injury from rotation.
